3. The mobile device according to claim 1, wherein the at least one processor is further configured to execute the instructions to:

receive in the P2P node a data packet sent by the one or more external electronic devices;

forward the data packet from the P2P node to the station node; and

send the data packet from the station node to the wireless access point for forwarding the data packet to a target device.

4. The mobile device according to claim 1, wherein the at least one processor is further configured to execute the instructions to:

receive in the station node a data packet sent from the wireless access point;

forward the data packet from the station node to the P2P node; and

send the data packet from the P2P node to the one or more external electronic devices.

5. The mobile device according to claim 1, wherein the at least one processor is further configured to execute the instructions to:

send a routing table to the Wi-Fi module, wherein the routing table comprises a route between an IP address for the P2P node and an IP address for the station node; and

send configuration information of a Network Address Translation (NAT) function to the Wi-Fi module so that the IP address for the P2P node is translated.

17. The mobile device according to claim 1, wherein the predefined channel does not interfere with a channel connecting the wireless access point and the station node in the mobile device.

6. A relaying method of a mobile device, the method comprising:

connecting with a wireless access point through a station node of a Wi-Fi module in the mobile device;

broadcasting login information to one or more external electronic devices;

connecting with the one or more external electronic devices through a Peer-to-Peer (P2P) node of the Wi-Fi module in the mobile device after the one or more external electronic devices have been verified based on the broadcasted login information;
